应用氮气防治套袋烟叶害虫效果研究
|
摘要
本文对套袋烟叶进行充氮气调,以验证氮气对套袋烟叶害虫的防治效果。结果表明,在温度高于20℃、氧气浓度低于2%、持续时间45 d的技术参数条件下,可以有效杀灭套袋烟叶内各种虫态的烟草害虫,因而充氮气调防虫可以作为套袋烟叶虫害防治的技术方式,解决套袋烟叶因套袋后熏蒸无法渗透而不能达到理想的熏蒸效果的问题。同时,充氮气调除了可以作为绿色生态的杀虫方式逐渐替代磷化铝等化学熏蒸剂杀虫外,还可以对醇化到期烟叶进行保质养护,满足延缓烟叶醇化需求,同时充氮还可以作为霉变等异常烟叶养护的有效应急处理手段。
In this paper,the bagged tobacco leaves were filled with nitrogen to verify the control effect of nitrogen on bagged tobacco leaf pests.The results showed that under the condition of temperature above 20 ℃,oxygen concentration below 2% and duration of 45 d,it could effectively kill various pests of tobacco in the bagged tobacco leaves.The technical method of bagged tobacco leaves pests control solved the problem that the bagged tobacco leaves couldn′t penetrate the fumigation after bagging and couldn′t achieve the desired fumigation effect. At the same time,the nitrogen-filled nitrogen could be used as a green ecological insecticide to gradually replace the chemical fumigant such as aluminum phosphide,and it could also maintain the quality of the alcoholized expired tobacco leaves to meet the demand for delaying the alcoholization of tobacco leaves.At the same time,nitrogen filling could also be used as an effective emergency treatment method for abnormal tobacco leaf maintenance such as mildew.
